JAMES M. RIDDLE, OF NE\V YORK, N. Y.

MECHANISM FOR EM PTYING CARS.

SPECIFICATION :t'orming part of Letters Patent No. 690,877, datedJanuary '7, 1902. Application filed May 1, 1901. Serial No. 58,328. (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMES M. RIDDLE, a

citizen of the United States, residing at Man hat-tan borough, New Yorkcity, in the county and State of New York, have invented new and usefulImprovements in Emptying Cars, of which the following is aspecification.

By means of an oscillating table or platform cars which are to beemptied of their contents-as, for example, coal or the likecan be tiltedas required to bring the contents to the outlet.

The invention is set forth in the following specification and claims andillustrated in the annexed drawings, in which- Figure 1 is a sideelevation of a dumping or emptying device. Fig. 2 is a sectional sideelevation of Fig. 1 in section along a: as, Fig. 3. Fig. 3 is an endelevation of Fig. 1, sectioned along y y, Fig. 1. Fig. 4 is a plan Viewof the device.

In the drawings the letter (1 indicates a table or platform adapted tosupport a track or rails onto which can be run a car or vehicle b. Therisers 0 can be made to receive a cross-beam or locking-pieces d, which,lying across the ends of the car, confine the latter, so that it cannotrun off the support a. These locks d can be readily laid into notches orseats arranged therefor in risers c. The table a has a segment e bracedor connected thereto by the spoke pieces or braces f, and the table (orits arms g) is supported in oscillating condition by pivot or gudgeonsh, resting on blocks or arms 4., carried bya suitable foundation orframework. Flexible connections or chains 75, connected with segment 6,are wound about drum Z, so that by turning the latter one way or anotheropposite ends of the platform or car are elevated. This drum can beturned or set by a worm-shaft m, whose gear 0 is driven by one oranother of gears 'n as the drum is to be set one way or another. Thegears 11 are shown on shaft p, suitably driven by an engine or source ofcan be alternately moved into or out of clutch by a rod or shifter q,connected by lever r and link 3 with lever or handle t, placed in reachof an attendant.

To prevent excessive rock or tilting of the platform, a link or rod 11.,with nuts or stops o, is guided through fixed riser or stop a. As oneshoulder or stop 4; or another comes against the post the tilt of thecar is arrested. The inner end of rod it is connected to arm 9 upon oradjacent to the gudgeons, so that as the arms g swing the rod slidesback and forth. This rod, as seen in the plan view of Fig. 4-, is guidedthrough or can slide back and forth in the post a; but the shoulders 01.enlargements 1), being incapable of slipping through this post, willarrest or confine the reciprocation of rodu within a certain limit.

The car is shown with an outlet or discharge l,as known, and from whichmaterial can pass into a chute 2 to be led to a vessel or other point.After the main portion has discharged any coal or matter resting at oneend or another of the car can, by raising such end, be caused to roll toor drop out of the exit 1 into the chute. The oscillating table allowstilting of the cars containing coal or other material to such angle ordegree as suffices for causing the same to run or pass from either endof the car to and out of the outlet.

What I claim as new, and desire to secure by Letters Patent, is

1. A device for emptying cars comprising an oscillating table orsupport, mechanism for tilting the support in one direction or another,and a stop for limiting the tilt or inclination of the support, saidstop consisting of a rod connected to the table so as to reciprocate orslide back and forth on the swing or tilt of the table, a post throughwhich the movable rod is guided, and stops or enlargements on the rodmade to impinge against the post for arresting or limiting the slide orplay of the rod substantially as described.

2. A tilting table or support provided with a segment, aflexibleconnection secured along the segment for tilting the support, a drum anddriving mechanism for actuating the connection, and gear-wheels andclutch mechanism for driving the drum in different directionssubstantially as described.

3. A rail or car supporting table having a stop-arm and the tilt of thetable substantially 1o segment, a pivot or gudgeons from which the asdescribed. table is movably suspended, a flexible con- In testimonywhereof I have hereunto set nection or chain connected to the segment, amy hand in the presence of two subscribing 5 drum made to engage thechain for tilting the witnesses.
